William H. Neidlinger (1863-1952) was an American composer, organist, and music educator who built a substantial catalog of sacred and secular vocal music during the late 19th and early 20th centuries. His compositional output reflects the aesthetic values of his era: singable melodies, clear harmonic language, and an understanding of the voice that made his work accessible to amateur and professional singers alike.
Neidlinger's "The Birthday of a King" remains one of his most enduring compositions, written with the directness and emotional clarity that characterize his best work. The piece has become a standard in Christmas programming, valued by directors for its musicality and by singers for its rewarding vocal line.
